If you travel often, you have probably bought a book from an airport bookstore. And, if so, chances are it was from Hudson Booksellers. Because they have so many people traveling on business visit their stores, they probably have a better idea of what is popular in the business genre than most retailers. And, lucky us, they’ve been releasing a “best books of the year” list the last few years which includes a business interest category. This years list is:

• The Silver Lining: An Innovation Playbook for Uncertain Times by Scott D. Anthony, Harvard Business Press
• What the Dog Saw: And Other Adventures by Malcolm Gladwell, Little Brown and Company
• Superfreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Buy Life Insurance by Steven D. Levitt & Stephen J. Dubner, William Morrow & Company
• Adland: Searching for the Meaning of Life on a Branded Planet by James P. Othmer, Doubleday
• Cheap: The High Cost of Discount Culture by Ellen Ruppel Shell, Penguin Press
